This essay uses play to examine a wider process in behavioral research: how classification helps produce behavioral data and shapes the explanations those data can support. It asks how juvenile actions are classified as play and become evidence for claims about development, evolution, and \u201chuman nature.\u201d I argue that the same analogies to adult behavior that help recognize and organize juvenile actions as play later reappear in explanations of the roles or capacities that play is proposed to develop. Examples show how such developmental hypotheses become entangled with culturally familiar narratives of gender and human evolution, particularly as scientific claims circulate publicly. A comparative anthropology of play should keep these evidentiary steps visible, distinguish adult analogies from demonstrated developmental outcomes, and situate play within immature primates' immediate social and material worlds.<\/jats:p>","DOI":"10.1002\/evan.70047","type":"journal-article","created":{"date-parts":[[2026,8,25]],"date-time":"2026-08-25T08:04:48Z","timestamp":1787645088000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Primate Play and the Classificatory Making of Human Nature"],"prefix":"10.1002","volume":"35","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5261-1773","authenticated-orcid":false,"given":"Iulia","family":"B\u0103descu","sequence":"first","affiliation":[{"name":"D\u00e9partement d'anthropologie Universit\u00e9 de Montr\u00e9al Montr\u00e9al Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,25]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1163\/156853974X00534"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1017\/CBO9780511810893"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.2307\/3178066"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1515\/9780691209753"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cub.2010.11.024"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1080\/21594937.2022.2152184"},{"key":"e_1_2_10_8_1","volume-title":"The Playful Brain: Venturing to the Limits of Neuroscience","author":"Pellis S.
